Abstract

La présente invention concerne un procédé de transmission de plusieurs trames dans un système de réseau local sans fil (WLAN) prenant en charge les entrées multiples sorties multiples multiutilisateur (MU-MIMO). Le procédé comprend la transmission d'une première trame et d'une deuxième trame de manière consécutive à une première station (STA) et la transmission d'une troisième trame et d'une quatrième trame de manière consécutive à une seconde STA, le moment de début de la transmission de la première trame et le moment de début de la transmission de la troisième trame étant alignés l'un sur l'autre et le moment de début de la transmission de la deuxième trame et le moment de début de la transmission de la quatrième trame étant alignés l'un sur l'autre.
